MOTOR.

SPECIFICATION forming part of Letters Patent No. 287,777, dated October 30, 1883.

\ '7 Application filed September 12. 1883. (No model.)

.Zo all whom it may concern:

Be it known that I, MASTIN L. BIsoN, a citizen of'the United States, residing at Clarksville, in the county of Montgomery and State of Tennessee, have invented a new and useful Motor, of which the following is a specifica- I tion, reference being had to the accompanying drawings.

This invention relates to motors such as are adapted to operate churns, fans, 850.; and its object is to provide'a motor possessing superior advantages in point of simplicity, inexpensiveness, durability, ease of operation, and general efficiency. l

In the drawings, Figure 1 is aside elevation of my improved motor. Fig. 2is a front elevation of the same. Fig. 3 is another side View, parts being broken away to show the construction.

Referring to the drawings, A designates the frame of my improved motor, which is secured in elevated position by any suitable means, and provides bearings for a main hori- 'zontal shaft, B, that carries a drum, O, hav

ing a ratchet-disk, D, at one end, a main gearwheel, E, being loosely arranged on shaft B adjoining this ratchet end, and retained in position against the drum by means of a spider plate or disk, F, held by a pin, G, passing through said shaft.

The gear-wheel E carries a spring-actuated pawl, H, that isretained in engagement with the ratchet D, so that when the drum is turned in one direction by action of the rope I, having the end weight, J, the Wheel E is carried with the drum and revolves therewith. As the rope I unwinds from the drum, the rotary movement of the latter causes a cord, K, to wind upon it, and when the rope I has unwound its entire length it can be rewound by simply drawing on cord K to turn the drum, during which movement the ratchet D will pass under the pawl and not engage thesame.

Thus the device can be easily kept in motion 7 by simply drawing on cord K at intervals.

the like.

The movement of wheel E is transmitted to a gear-wheel, L, on the main operating-shaft M by means of an intermediate gear, N, or a train of gears, and from this shaft M the power is applied to drive the 'churn-dasher, fan, or

To effect this the shaft M is provided with a crank, O,'at one or both ends, which is connected to the fan or dasher, a

rock-arm, P, being preferablyemployed, as

shown. This rock-arm is formed with a lon gitudinally-disposed slot, Q, in which works the crank O, and is pivoted to the frame A, as at R. The handle or staff S of the fan'or the device to be operated has then only to be secured to the rock-arm.

The operation and advantages of my inventionwill be readily understood. and convenient, and can be easily governed.

I claim asm invention- 1. The combination 'of the frame of the motor, the main operating-shaft having crank It is simple ends, means for operating said shaft and the rock-arm hinged to the frame and formed with the slot in which moves the crank, substantially as and for the purpose set forth.

2. The combination of the frame of the motor, the main horizontal shaft carrying the drum, said drum having the ratchet teeth or disk at' its end, the winding cord wound on the drum in one direction, and the weighted rope wound on the drum in an opposite direc tion, the main gear-Wheel loosely-arranged near to the ratchet and carrying the springactuated pawl, the operating-shaft having the gear-wheel and crank ends, the train of intermediate gears, and the pivoted and slotted rock-arm, substantially as and for the purpose set forth. i

In testimony that I claim the foregoing as my own I have hereto affixed my signature in pres ence of two witnesses. I
